The present invention relates to improvements in powder boxes. 7 r i In this improved powder box the mass of the powder contained in the body of the box is subjected to a sudden impact under the action of the closing of the lid, which compels it to pass through a sieve on which rests freely the powder puff. V l

' The accompanying drawing illustrates, by way of example, the'imp'roved powder box. v

Figure 7 illustrates, on an enlarged scale, the closing member.- I

Figures 8a, 8b, 8c, 8d illustrate the various phases of the closing operation.

As illustrated in the drawing, this powder box is composed of a box proper land of a lid 2 connected together by a hinge,

In the bottom'of the body of the box is arranged a small resilient and deformable domed metal plate 3 provided with lugs 4 and having at its centre a swelling 5 in order to give it a certain rigidity. j

-This resilient plate 3 is covered with a washer 6 made of cloth and forming thebase on which the powder rests. p The box body is closed by a crown 11 havin g at its centreone or more removable sieves 12. The sieve or sieves may be replaced by a perforated plate. The sieve or plate being removable allows powder to be introduced into the box body and rest on the member 6 and thereby on the plate 3 A stiff resilient lever 7 is secured at one end to the under side of the crown 11 whilst its other end is free and passes upwardly through an opening in the crown. I

This lever 7 bears upon the swelling 5 of the plate 3 and its freeend is provided with a claw or curve of any shape adapted to lever hold the lid 2 in the closed position, by engaging above an inwardly projecting lip 16 on the lid.

Theoper ation of this powder box is as follows:

. When the powder box has been filled with powder'and provided with a powder puff 15 placed freely on the sieve (Figure 8a) the box is closed by pressing on the lid 2. On closing the box, on account of the arrangement and 6 shape of-thefreeend of the lever 7 (see Figure 7 and the following figures), the lip 16 on the box lid presses down the free end 10 of the lever 7. The middle part of this leveriis thus pressed down on the central swelling of the plate 3 and depresses this plate at its cen-' tre. At this moment the end of the lever 10 is in positionindicated in Figure 8b.. The closing movement continues and the end 10 of the lever 7 is moved backwards (Figure 8c) on'account of the shape of its head and the provision of the flange 13 on the crown 11. This movement frees the end 10 of the lever 7 from the pressure of the lid 2 and consequently relieves the plate 3 from the pressure ofthe lever 7 The plate 3 consequently snaps up suddenly into its original shape (Figure 8d). a The eflect of this is first to push the 7 upwards so that its free end engages under the lip 16 on the box lid and thereby looks the lid in the closed position, and secondly to impart a strong upward impact'to the powder resting on the member 6. The powder is thus made to pass upwards through the sieve and come onto the powder puff g resting on the sieve.

For controlling the quantity of powder passing through the sieve, upon each closing operation of the powder box, it is convenient to provide two superposed sieves'arranged at a distance from each other. This arrangement facilitates the formation of a layer of powder between two sieves. However, these sieves might be replaced by a simple perforated plate.

The device described above allows the powder to be automatically spread upon the pow der puff, this automatism depending solely on the closing'of'the lid ofthe powder box.

Figure 5 shows a constructional modifica- In the various forms of construction considered, the operation is always the same. Under the action of the closing of the lid, a lowering movement takes place, followed by a sudden upward jerk of the surface on which the powder rests this causes a certain quan tity of powder to be thrown upwards through the perforated plate or. sieve on which freely rests the powder puff which thus receives powder.

. The device describedpermits the quantity of powder passing through the sieve or the perforated plate to be regulated by altering the resiliency of the flexible parts and the weft of the sieve or the perforations.

Iclaim:

1. Powder box comprising a box body, a lid hinged on this body, a crown on this body, a powder sifting surface at the centre portion of this crown, a resilient and deformable plate at thebase of the box and on vwhich the powderrests, a stiff resilient lever connected atone end to the underside of the crown and at the other end projecting upwardly through an opening in this crown the middle portion of this lever bearing, on the said domed plate, an inwardly projecting lip on the box lid and a part on the free end of the lever adapted to engage over this lip when the box is closed whereby a downward movement of the lid to close the box first depresses the said lever so as to deform the said base plate and then causes the said lever to snap over the said lip and relax the said base plate suddenly.

2. Powder box comprising a box body, a lid hinged on this body, a crown on this body, a removable perforated surface at the centre portion of this crown, a resilient and deformable plate at the base of the box and on which the powder rests, a stiff resilient lever connected at one end to the underside of the crown and at the other end projecting upwardly through an opening in this crown the middle portion of this lever bearing on the said domed plate, an inwardly projecting lip on the box lid and a part on the free endof the lever adapted to engage over this lip when the box is closed whereby a downward movement of the lidto close the box first depresses the said lever so as to deform the said base plate and then causes the said lever to snap over the said lip and relax the said base plate suddenly. V Y

3. A powder box comprising a box body, a lid hinged on this body, a crown on this body, a powder sifting surface" at the centre portion of this crown, a resilient member at the base of the box and on which the powder rests, a stiff resilient lever connected at one end to the under side of the crown and at the other end projecting upward through an opening in this crown, the middle portion of this lever bearing on the said resilient member, an inwardly projecting lip on the box lid and a part on the free end of the lever adaptedto engage over this lip when the box is closed, whereby a downward movement of thelid to close the box first depresses the said lever so as to deform the said resilient member, and then causes the lever to snap over the said lip and relax the said resilient member suddenly.

4. A powder box comprising a box body, a lid hinged on this body, a crown on this body, a powder sifting surface at the centre portion of this crown, a domed resilient and deformable plateat the base of the box and on which the powder rests, a stifif resilient lever connected at one end to the under side of the crown and at the other end projecting up ward through an opening in this crown, the middle portion of this lever bearing on said deformable plate, an inwardly projecting lip on the box lid and a part on the free end of the leveradapted to engage over this lip when the box is closed, whereby a downward movement of the lid to close the box first depresses the said lever so as to deform the said deformable plate, and then causes the lever to snap over the said lip and relax the said deformable plate suddenly.

5. A powder box comprising a box body having an inwardly domed resilient and deformable base, a crown on this body, a lid hinged on this body, a removable perforated surface at the centre portion of this crown, a stifi resilient lever connected at one end to the under side of the crown and at the other end projecting upwardly through an opening in this crown, the middle portion of this lever bearing on a block carried on the said domed base,an inwardly projecting lip on the box lid and a part on the free end of the lever, adapted to engage over this lip when the box is closed, whereby a downward movement of the lid to close the box first depresses the said lever so as to deform the said base and then causes the said lever to snap over the said lip and relax the said base suddenly.

6. A powder box comprising a box body, a lid hinged on this body, a crown on this body, a powder sifting surface at the centre of this crown, a plate at the base of the box and on which the powder rests, this plate having downwardly bent deformable andresilient arms whereby the plate is supported on the base, a stiff resilient lever connected at one end to the under side of the crown and at the other end projecting upward through an opening in this crown, the middle portion of this lever bearing on the said plate, an inwardly projecting lip on the box lid and a part on the free end of the lever adapted to engage over this lip when the box is closed, whereby a downward movement of the lid to close the box first depresses the said lever so as to deform the said plate, and then causes the lever to snap over the said lip and relax the said plate suddenly.
